目前,我省水稻生产正逐步向两高(高产、高效益)、一优(优良品质)的目标转化。推动水稻生产向这一目标转化的动力是由多个水稻单项技术改革组成的综合技术措施,其中合理稀植技术是一项重要内容。1982年以前,我省水稻多采用9×3寸的栽植形式,部分用8×3寸或7×3寸形式,每亩基本苗达11—15万之多。在这种高密度情况下,常因水肥管理跟不上而导致水稻倒伏、感病和品质下降。密植栽培在很大程度上构成了水稻高产稳产的限制因素。
At present, rice production in our province is gradually transforming into the goal of “two highs (high yield and high efficiency) and one excellent (excellent quality)”. The driving force for promoting the transformation of rice production to this goal is a comprehensive technical measure consisting of a number of rice technical innovations, of which rational sparse planting is an important element. Before 1982, the rice in our province was mostly planted in the form of 9 × 3-inch and partly in the form of 8 × 3-inch or 7 × 3-inch. In this high density, often due to water and fertilizer management can not keep up and lead to rice lodging, flu and quality decline. Close planting cultivation to a large extent constitutes a limiting factor for the high and stable yield of rice.
